Abstract

L'invention concerne un circuit (30, 40) pour la production d'une tension de sortie (Vout) avec séparation de potentiels, à partir d'une tension de secteur (Vin). Cel circuit comprend un circuit de correction de facteur de puissance (CFP) (31) possédant une inductance (L31) alimentée par la tension de secteur (Vin) et un commutateur (T31) commandé, qui régule la charge et la décharge de l'inductance (L31), et au moins un transformateur de séparation de potentiels (N1- N2, N1'-N2') qui assure une séparation galvanique entre la tension de sortie (Vout) et la tension de secteur (Vin). Lors de la décharge de l'inductance (L31) une première partie de l'énergie stockée par l'inductance pendant la charge est fournie au transformateur de séparation de potentiels (N1-N2, N1'-N2' ).
